Adductor-Canal-Blockade Versus the Femoral Nerve Block Effect on Muscle Strength, Pain and Mobilization After Total Knee Replacement

Not Applicable

Completed

• Conditions: Total Knee Arthroplasty
• Interventions: Procedure: Adductor-Canal-Blockade; Procedure: Femoral Nerve Block

• Registration Number: NCT01470391
• Lead Sponsor: Rigshospitalet, Denmark

Brief Summary

The aim of this study is to investigate the efficacy of the Adductor-Canal-Blockade versus the Femoral Nerve Block on muscle strength, pain and mobilization after total knee arthroplasty. We hypothesize that the Adductor-Canal-Blockade has the same effect on pain and morphine consumption as the Femoral Nerve Block, but without the same reduction in quadriceps muscle strength.
